Bonjour, voilà, je pense que c'est ça, je te conseille de souligner tous les verbes ça sera beaucoup plus claire. Bonne journée, j'espère t'avoir aidé (e).
Last night I was reading reedega book when I heard at the clock. It was 10pm. My flat mate had told me that he would be back at 12, so I knew it couldn't be him. I was walking to the window and was looking out. A man was standing outside in the dark. I was screaming loudly “I’m calling the police!” Then my flat mate opened the door. He laughed at me. I found out later that it was 12 o'clock. The clock had stopped.
